SPECIFICATION forming part of Letters Patent No. 599,230, dated February15, 1898. Application filed February 27, 1897. Serial No. 625.352. (Nomodel.)

To all whom, t may concern:

Beit known that I, OSCAR FRorscHEa, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a certain new and useful Improvement inW'indows, of which the followingr is a speciiication, reference beinghad to the accompanying drawings.

This improvement relates to that class of windows in which the sashesare pivotally connected with sliding cleats, so as to be tilted orreversed for the purpose of cleaning or otherwise; and the object of theimprovement is to provide a window of this class that can be cheaplymade, will be convenient in use, and not likely to get out of order.

To these endsthe invention consists in the peculiarconstruction,arrangement, andcombinations of parts hereinafter more particularlydescribed and then definitely claimed.

In the accompanying drawings, Figure l is a vertical central section ofa windowconstructed according to myirnprovement, showing the sashesclosed in full lines and tilted in various positions in dotted lines.Fig. 2 is a horizontal section of part of a Window, on alargerscale,with both sashes down. Fig. 3 is an isometrical perspective Viewof one side of a sash. Fig. iis a horizontal section showing amodification of the pulley-stile. Fig. 5 is a vertical section of partof the stile of a sash. Fig. 6 is an isometrical perspective view of ahanger, chain, and pivot.

Referring now to the details of the drawings by numerals, l indicatesthe sill, 2 the casing, and 3 the pulley-stile, of the frame, the stilebeing provided with grooves 3', preferably of the form shown in Fig. 2or Fig. 4, in which slide the cleats 4, set in grooves 6 in thesash-stile 7, in which last-mentioned grooves they are secured by screws8, (see Fig. 5,) passing through holes in the cleats into thesash-stile. Surrounding the major part of the shanks of these screws arespiral springsQ, which partly set in holes lO, bored in the sashstile.Instead of spiral springs iat platesprings may loe used, as indicated atll in Fig. in which case the holes will be unnecessary. Projectingthrough the cleats are pivots l2, having at one end plates 13, by whichthey are secured to the sashes, and at the other end `for the outerweight inside the casing. sides this the thick stiles increase thestiff- 7o grooves le!E to receive the hangers l5, having two hooks tocatch into the chain 16, which passes over the pulley 17 to receive thesash- 55 ing toward the outside and forming the pro- 6o j ections 1S,which serve on the lower or inner sash to give space (ordinarilyprovided by the parting-bead) for the usual joint between themeeting-rails 19 20. (See Fig. l.) On the upper or outer sash it helpstofill the space usually occupied by the outer bead and covers up theouter part of the pulley-stile, which part is necessarily made wide toafford space ness of the sashes and form sufficient thick ness in thestile to allow of the formation of the groove for the cleats withoutweakening the stiles.

The pulleystile, if made as in Fig. 2, can 75 be cut across its fullwidth, as indicated by the line 2l in Fig. l, and thus the pocket piecefor the insertion of both weights can be removed in one piece for thefull width of the stile, thus avoiding the necessity of vertical 8o oncurved lines instead of on straight lines,

in which case the cleats should of course have the same contour on thecontiguous parts. I should consider both these forms of grooves andcleats as equivalents of each other, and

where Irefer hereinafter to inclined edges 9o I mean to be understood asincluding both of these forms.

It will be observed that with the above constructions imparting-bead isrequired and no checks or beads inside or outside to hold the sashes inplace, the bead 22 being merely used as a matter of finish and having noother function.

With the above constructions the sashes may be raised and lowered in theusual man- 10o ner, and if it is desired to reverse them for cleaning orother purposes the lower sash can be turned, as indicated by the dottedlines 23 in Fig. l, and the upper one, when it has been lowered and thelower one raised, can be turned in the position indicated by the dottedlines 24 in the same figure; or both sashes can be turnedsimultaneouslyin the position indicated by the dotted lines 25 in Fig. 1for Ventilating purposes. This movement can be made in any position ofthe sashes. To make the sashes assume any of these positions, it is onlynecessary to push on the lower rails of the sashes. This will cause thecleats to rise over and out of the inclined edges of the grooves in thepulley-stiles, the springs between the cleats and sash yielding to allowthis, and thus the sashes can be turned in any desired position. When itis desired that they shall assume their normal position, it is onlynecessary to turn the sashes to a vertical position, when the cleatswill be forced by the springs into the grooves, and the sashes can bemade to slide up and down in the usual manner. From this it will be seenthat I have invented a very convenient window that is easily made andoperated and one not likely to get out of order.

I am aware of theexpired patent, No. 30,095, issued to L. YV. ThickstunSeptember 18, 1860, in which sashes are shown provided with strips thatare moved in and out of grooves in the frame by means of spirallygroovedfastening devices; but these sashes are incapable of being swung ontheir pivots by simply pushing them, as they must irst have the stripswithdrawn by turning the fastening devices before referred to.

I am also aware that it has been proposed to make a weather-strip on ahinged door with round edges, as shown in the Patent No. 399,413, issuedto Jones March 12, 1889; but there is nothing in said patent to indicatethat the inventor ever had any idea of using it in the manner shown inmy improvement.

I am further aware of the Bolles patent, No. 554,231, dated February 11,1896, in which there are shown sashes provided with yielding cleatsworking in the ordinary windowframes; but in this case the suspendingmeans, instead of being attached to the pivots on which the sash turns,are secured to the cleats, so that the whole weight of the sash hangsupon them, which makes them comparatively hard to move, and thereforerequires much stronger springs than is necessary with mine, in which thecleats are free to move and require but light springs to keep them inplace, because my sashes are hung directly on the pivots, and there isthus but little friction to prevent the easy yielding of the cleats.Moreover, in the window shown in this patent the majority of the springsare necessarily arranged to bear on the grooves in the stiles, and arethus liable to mar and discolor the paint in the upper parts of thegrooves, whereas in my improvement the springs are set between thecleats and the sashes and cannot, therefore, mar the paint.

I am also aware of the Rudolph patent, No. 207,305, in which the pivotsare connected with the suspending-cords by means of the springs. Thisarrangement is objectionable, inasmuch as it requires the springs to beperforated to receive the pivots, which weakens the springs, renderingthem liable to be broken, thus sundering the connection between thepivots and the suspending means. Moreover, as no spring can be used atthe upper part of the sash for want of room, the sash depends for itsaction on the suspending-spring alone, which, as before stated, isliable to be broken. In myimprovement, on the contrary, the weakening orbreaking of either one of the springs would have no effect, and I amthus able to combine the advantages of freedom from the friction of thesprings, the plurality of springs, and the direct connection between thepivots and the suspending means.

What I claim as new is- 1. In a window and in combination with a sashhaving a groove in its sides, a cleat set therein havingoppositely-inclined edges, springs operating to push said cleat outwardset between the cleat and sash, al pivot fast on the sash and passingthrough the cleat, suspending means attached to the pivot, and apulley-stile having grooves with oppositelyinclined edges and adapted toreceive the oppositely-inclined edges of the cleats, substantially asdescribed.

2. In a window, the combination of a sash having grooves in its oppositevertical edges, cleats set therein having oppositely-inclined edges,springs operating to push said cleats outward, arranged between thesashes and cleats and a pair of pulley-Stiles having oppositely-inclinededges and adapted to receive the inclined edges of the cleats, withpivots fast upon the sashes and projecting through the cleats to receivethe suspending devices, substantially as described.

In testimony whereof I affix my signature, in the presence of twowitnesses, this 26th day of February, 1897.
